I've noticed recently with my HWS that on live and recorded tv, then occasionally the hd picture will pixelate for a sec like it is starting to lose signal. Yesterday while watching an HD movie on HBO, twice during the movie then it did the " lost signal, switching to SD equivelant" , but then I immediately hit channel up and it went back to the HD one and worked fine. I checked my dish and I don't see anything obstructing it, well, maybe a weed that is on the outer edge of it, but I've seen lots more weeds than that before and it didn't affect it at all. Last winter, Dish moved my dish to right beside the house with the post concreted in the ground. Is it possible that it has started to change it's alignment? I just now checked my signal numbers... on 110 spotbeam 1 signal is 64, 119 spotbeam 1 signal is 45, and on 129 spotbeam 1 signal is 48. How do these numbers sound, thanks!
